Question

The length of a rectangle is three meters less than twice its width. If the perimeter of the rectangle is 66 meters, find its dimensions. Write your answer as two numbers separated by a comma

Answer 1

Answer:

assume it's width as 'x'

So, it's length is '2x-3'

and the perimeter is equal to 66m

Step-by-step explanation:

So,equalize the equation

x + (2x-3) + x + (2x-3) = 66

remove the brackets

2x + 4x - 6 = 66

add 6 to both sides

6x = 60

x = 60 ÷ 6

= 10

so, the length is 2x-3 = 20 - 3 = 17 m

and the breadth is x = 10 m
